1. A process for removing a molybdenum-alloy refractory metal core from a turbine blade through sublimation comprising:
installing at least one turbine blade in a sublimation fixture;
installing said sublimation fixture in an interior of a retort furnace, a flow passage thermally coupled to said retort furnace configured to heat air flowing through said flow passage and deliver said heated air to a molybdenum-alloy refractory metal core;
supplying the air from an air source to a coupling fluidly coupled to said flow passage;
heating said air flowing through said flow passage;
supplying said heated air from said flow passage to a junction; coupling said junction to said sublimation fixture;
removing the molybdenum-alloy refractory metal core from said at least one turbine blade through sublimation with said heated air; and
capturing waste discharged from the blade responsive to sublimation of said molybdenum-alloy refractory metal core responsive to said sublimation.
